suman SQUAWKER.

Application filed December 10,192?. Serial No. 239,049.

Y My invention is concerned with What I call a siren squawker, and'is .an exceedingly sim ple Construction which can be cheaply manufactured, and which can be used to produce a n musical note or sound that can be varied in pitch, by blowing feebly into it, so that it can be operated by a baby or a. very small child.

To illustrate my invention, I anneX hereto a sheet of drawings, in which the same refer- .0 ence 'characters are used to designate identical parts in all the figures', of which,

F ig. lis a perspective view of the device;

Fig 2 is a plan View in central, horizontal section; Fig'. 3 is a plan view of the supportmg wire detached; o L

Fig. 4 is a perspective view of the mouthpiece; and

Fig. 5 is a perspective view of the rubber before the same has been attached.

In carryi'ng out my invention 'in its pre- :ferred form, I employ a tubular mouthpiece 10, which is conveniently made of Wood and has one endoll shaped to fit the lips, and the other end provided with an annular channel or groove 12 to receive the thiokened end 13 of' the rubber 14. A pair of flanges 15'and 16 may be empl0yed,:leaving a cylindrical space between them around which may be pasted or otherwise Secured the paper or celluloid strip 17 carrying any desired legendor .adverti-sing matter.

The supporting member preferably consists of a piece of wire having the central loop portion 18, which is of the proper size to Spring into and be securely held in the endof the tube of the mouthpiece, as will be readlly apparent in Fig. 2. On either side of the central portion are the arms 19, which preierably 4o have the humped portion 20 and terminate in the short closed loops 21, so 'that When .the rubber tube is stretched over the. same with the thickened end 13 fitting in the channel 12, most of the body of 'the tube will be stretched over the wire tightly enough so that When air s blown through the tube a musical tone will be produced. Thepitch of this tone can be raised by blowing harder or by cutting off a portion of the vibrating surface by graspmg a 5o portion of' the -vibrating outer end adjacent one or both sides between the thumb and finger.

While I have shown and described my invention as embodied in the form which I fin present consider best adapted to carry out its purposes, it will be understood that it is' ca pable of modlfications, and 'that I do not desire to b'e limited in the interpretation of the',

following. claims eXcept as may be necessi4 tated by the state of the prior art.

What l claim as new, and desire to secure by Letters Patent of the United States, is 1. *In a device of the Class described, the combination with a tubular mouthpiece having a supporting member on the outer end. thereof, of a piece ol' elastic flexible material' stretched on said supportmg member so as to produce a plane suri'ace under tension extending inthe directon oi' the air blown through the mouthpiece and beyond it. 4

2. In a device of the class described, the

combination with a tubular mouthpiecehaw' piece and adapted to stretch the tube beyond the mouthpiece so that air 'blown through the mouthpiece will vibrate the stretched portion of the tube. i

4. In a device of the class described, the.

combination with a tubular mouthpiece, oi: a short tube of elastic flexible material adapt ed to fit over the outer end of the mouthpiece. and a supporting member carried by the mouthpiece and adapted to stretch the outer end of the tube beyond the mouthpiece so that air blown through the mouthpiece will vi brate the stretched portion of the tube.

5. In a device of the Class described,-the.

combination with a tubular mouthpiece, of a short rubber tube, and a supporting member carried by the mouthpiece and adapted to stretch the 'tube beyond the mouthpiece so that air blown through the mouthpiece will.

vibrate the stretched portion of the tube.

6. In a device of the class described, the combination with a tubular mouthpiece, of a short tube of elastic flexible material, and a supporting member comprising a stem por tion adapted to fit in the outer end of the Luv which the tube of elasti'c. material is adapted' to be stretched beyond the mouthpiece.

y 8. In a device of the clase described, the 'combination With a tubular niouthpece, ol'a short tube of elastic flexible material, and a Wire su pportin g inern'ber coinprising a central stem or loop portion Adapted to lit in the outer end of the tubular mouthpiece anda' pair oi? Widel'y 'separated arms over which the tube of elastic material is adapted to be stretched beyond the inouthpiece, said arms liaving their end's i'urn1shed'w1th short closed loops.

9, In a device of the clas-s described, the: combination With a tubular inouthpi'ece naving an annular groove near its outler end, of a short tube of elastic flexible material having one'end thickenecl and adapted to fit tightlyin said* annular groove, and a supporting, i Inember carrled by the inouthpiece and adapted to stretch the other end oi the tube so that air blown through the inouthpiece will Vibratetbe seine.

10. In a device of the Class described, the

combination With a tubular mouthpiece having an annular groove near its outer end, of a short tube of elastic fleXible material'having one end thickened and adapted to fin t' tightly in said. annular groove, and a supporting t a short tube ofelastic flexible material having one end thickened and adapte'cl to fit tightl y in said ann uIar groove, and a supporting member carried by the mouthpiece and adapted to stretch the other end of the tube so that air blown through the mouthpiece will V-- brate the same, said supporting:memberco mprsing a Wire having a central stem or loop portion adapted to fit in the outer endofthe tubular mouthpiece and a 'pair of wicIey separated arms over :which the tube is' stretched.. A

12. In a device of the Glass described the combination With a tubular mouthpiecehaving a rounded outer end' to fitbetween the lips, au annular groov-e near itsother end', and a plane cylind'rical surface between* the outer end. and the' groove,l.of a short tube of elastic flexible material having a tliickened inner endadaptedto fittightly in tlle annular groove, and. a supporting member carried' by the inouthpiece and ad'apted to streteli tbe tube so that air blowm throughr the inout-'lipiece willvbrate the stret'ehed porti ou thereof. i i o In. witnesswhereof, I have hereuntoset my band this 6th day of December, .1927.
